Debian GNU/Linux is legendary and would be absolutely my favorit if they
would not have that social contract saying they will support non-free
software. I don't want to support non-free software.
It is interesting that there is interest inside Debian to become FSF approved
distribution, and that they have a mailing list for it.
What is even more interesting is that you can make a difference in Debian, at
least try to. Make proposals, post on mailing lists, get a voting solution
for your proposal and make the change. Debian is a great democracy.
This is very inspiring and refreshing to see that there is still people
trying to make the change.
